Reinformed Ball Reducer SFP series
A Ball Reducer featuring increased allowable torque due to its improved cycloid curve in the torque transmission section, its allowable radial load has also been enhanced by using three-point support for its output shaft bearing.
Technical InformationHighlights
-
Improved Load Capacity
Boasts improved allowable radial load of the output shaft and enhanced rigidity, with every component upgraded based on the BR Series.
-
Zero-Backlash
Uses a steel ball in the deceleration mechanism instead of a gear. Eliminates backlash and enables prevision feeding and high-precision positioning through constant rolling contact via preload.
-
Compact & Simple
Has a reduction mechanism and input/output bearings built into its housing for compactness and ease of installation.
-
Motor Attachment Standardization
The SFP Series has standardized motor attachments for servo motors of various manufacturers, allowing the motor to be immediately installed after purchase.
-
Maintenance-free
Its grease-filled reducer can be used without lubrication for its entire rated life. Also has no mounting position restrictions.
-
High Efficiency
Its transmission mechanism uses a large number of steel balls to achieve a high-efficiency drive. The rolling contact of the balls is similar to that of a ball screw, allowing extremely light operation and maximized capacity of any motor.
